Step 1: Consider plasmasConsider the two types of flat-screen TVs: plasma and LCD. Plasma screens are larger and provide a more vivid picture, and are easily viewed from different angles.*Tip: On the other hand, still images -- such as network logos -- can "burn in," or become permanently visible, on some plasmas, though that's becoming less of a problem.

Step 2: Consider LCDsNow weigh the merits of the LCD. It's lighter and less fragile than a plasma, uses less electricity, is easier to install, and there's no danger of burn-in. But the LCD picture is also less vivid. A good general rule of thumb is if you are looking for less then a 50-inch screen, then go with LCDs.

Step 3: Consider resolutionConsider if you want to pay for a higher resolution — that is, a sharper picture than what comes standard with a plasma or LCD. There are several upgrades.

Step 4: Comparison shopOnce you've decided what you want, its time to comparison shop, either in person at your local electronics store or online. Compare TVs by brand, price, and features until you find the one that's right for you.
